Specification of Letters Patent.

Patented Nov. 26,1912.

Application filed February 4, 1911. Serial No. 606,557.

To all whom it may concern:

Be it known that I, LESLIE MCMINN, a citizen of the United States,residing at- Knoxville, in the county of Knox and State of Tennessee,have invented new and useful Improvements in Telephone-Bells, of whichthe following is a specification.

This invention relates to telephones and more particularly to telephonebells.

The invention has for one of its objects to provide an extremely simpleand practical bell which gives out a pleasing sound which is at the sametime loud enough to be used for telephone service.

Another object of the invention is the provision of a bell whichincludes a single gong and striking hammer, the gong having in ternalmembers spaced apart and between which the hammer moves to strike thememhers alternately.

lVith these objects in view and others, as will appear as thedescription proceeds, the invention comprises the various novel featuresof construction and arrangement of parts which will be more fullydescribed hereinafter and set forth with particularity in the claimappended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention, Figure 1 is a perspective view of a telephone equipped withthe improved bell. Fig. 2 is a sectional view through the gong to showthe relation of the hammer to the in ternal striking members of thegong. Fig. 3 is a perspective view of the rear side of the gong.

Similar reference characters are employed to designate correspondingparts throughout the views.

Referring to the drawing, A designates an ordinary telephone ortelephone ringing box which contains the usual electro-magneticallyoperated hammer 1 that is adapted to strike the single gong 2, thesingle gong being designed to take the place of the double gongs with astriking hammer disposed between them as are now in common use. Thisgong is attached to the box of the telephone by a post 3 and is sopositioned that the two spaced parallel striking members 4 and 5 aredisposed respectively on opposite sides of the hammer. These members 4and 5 are extremities of a U-shaped structure which has its base 6bearing on the internal surface of the gong and fastened rigidly to thelatter by a rivet 7 or equivalent fastening. This U-shaped structure isdisposed wholly within the hollow of the gong so as not to interferewith the latter being brought close to the ringer boX. When the hammervibrates, it will alternately strike the members l and 5 and cause avery agreeable sound to be emitted which is loud enough to be distinctlyheard within a reasonable radius. The base or bar 6 is curved to fit thecurvature of the rim of the gong so that the U-shaped structure willhave a large surface contact with the gong and at the same time snuglyfit the latter and prevent a jingling sound which would otherwise resultif the U-shaped structure were loose and did not snugly fit the gong.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimappended hereto.

Having thus described the invention, what I claim as new, is

The combination of a telephone including a bell hammer, a hollow gongdisposed over the hammer and having a circular rim, a horizontallydisposed Ushaped member mounted within the said gong, said U- shapedmember having a central curved bar conforming to the curvature of thesaid rim and adapted to be attached to the inner wall thereof whereby tosecurely hold said member in an operative position within the said gong,said member being formed to provide In testimony whereof I afiix mysignaspaced parallel arms projecting inwardly ture in presence of tWoWitnesses.
